Which waste category is often described by having BOD, COD and Ammonia as key characteristics?

Explanation:
BOD and COD measure how much organic pollution is present, while ammonia reflects nitrogen-containing compounds in the wastewater. Oil refinery effluent commonly contains substantial organic matter from hydrocarbons and process solvents (pushing both BOD and COD up) and also contains ammonia from certain process streams and catalyst-related waste. This combination—high biodegradable and total organic content along with notable ammonia—is a typical hallmark of refinery wastewater, more so than the other industries listed, which tend to dominate with different pollutant profiles (color and chlorinated organics for pulp and paper, mainly inorganic loads for steel, etc.).
